GMPLS OSPF-TE Extensions in Support of Flexi-Grid Dense Wavelength Division Multiplexing Networks
RFC 8363, “GMPLS OSPF-TE Extensions in Support of Flexi-Grid Dense Wavelength Division Multiplexing Networks”, is a Proposed Standard document published in May 2018 by X. Zhang, H. Zheng, R. Casellas, O. Gonzalez de Dios, D. Ceccarelli. The canonical text is published by the RFC Editor.
Abstract
The International Telecommunication Union Telecommunication standardization sector (ITU-T) has extended its Recommendations G.694.1 and G.872 to include a new Dense Wavelength Division Multiplexing (DWDM) grid by defining channel spacings, a set of nominal central frequencies, and the concept of the "frequency slot". Corresponding techniques for data-plane connections are known as "flexi-grid".
Based on the characteristics of flexi-grid defined in G.694.1 and in RFCs 7698 and 7699, this document describes the Open Shortest Path First - Traffic Engineering (OSPF-TE) extensions in support of GMPLS control of networks that include devices that use the new flexible optical grid.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
